BRICK WALL cons'rauorron.

Application filed September 15, 1924. Serial No. 737,744.

The invention relates to brick wall construction.

The invention is more particularly concerned with providing a removable. facing, composed of brick, without injuring or removing the wall structure as a whole.

The invent-ion furthermore contemplates a brick facing in which overlapping bricks break joint throughout the wall structure, as rin the usual manner of building walls,

the composition of the wall and facing being such that the entire facing may be removed without taking away from the wall more than one-half of a brick in width, thereby leaving the major part of the wall standing and in condition to cooperate in the same manner with a new similar facing to be subsequetly applied thereto.

The invention is especially adapted for walls enclosing a furnace in which the inside facing is composed of removable re brick and the remainder of the wall of lire brick or common brick. In such walls, as usually constructed, the header course is composed of fire brick in which the brick are laid with their longest axes in planes transverse to the linear direction of the wall. The header bricks, therefore, extend largely across the entire width of the wall $0 so that to remove them it would be necessary to tear down the entire wall.

In boiler settings the inner wall facing, Within the furnace, isI subjected to Very high temperature which tends, in course of v time, to disintegrate and destroy the fire bricks ot' the wall to such an extent that a new wall or a new facing becomes necessary.

In the practice of my invention the entire inner lire brick facing may be removed 4o from the permanent wall composed of lire brick or common brick, without disturbing or injuring the load supporting part thereof, and a new facing of tire brick may be replaced and have the same relation with the brick remaining in the wall as in the original structure.

The object of the invention will become apparent from the above statement.

Other objects, advantages and` benefits will be understood from a consideration of the following description when taken in conjunction with the drawings forming a part hereof, wherein :e-

Fig. 1 shows the top of a wall comprising the header course made of two special type bricks.

.wall will be left standing.

F ig. 2 is a similar view showing a stretcher course. v

Fig. 3 shows a fragment of a wall built up in accordance with this invent-ion showing a fire brick face.

F ig. 4 is a perspective View of an ordinary tire brick.

Fig. 5 is a similar view4 showing special forms of brick adaptable for use in carrying my invention into effect.

In all the views the same reference characters are employed to indicate similar parts.

The standard iire brick, as shown in Figs. 2 and 4, conforms so nearly in size with the common brick that 'they may be used interchangeably therewith in so far as dimensions are concerned.

The dimensions of the fire brick are approximately 9 inches in length by 41/2 inches in width and 21/2 linches thick. In the special forms of brick, shown in Fig. 5, the major part 10 is approximately 6% in length by 41/2 wide and 2%, thick. 80

The minor brick or portion 11 is 2% inches square in cross section by 41/2 incheslong. It may, however, be 9 inches long if desired.

The brick 13 and 11 are equivalent in 85 length, when taken together, as the standard brick 12.

In the wall structure 10 shown in Fig. 3, I have the re brick facing indicated by reference characters 11 and 12 and the brick 90 composing the supporting wall by reference characters 13. In this structure A, B and C are the intermediate stretcher courses and D are the header courses.

From an inspection of Fig. 3 it will ap- 95 pear that the facing fire brick 11 and 12 may be removed and that this facing does not extend more than 1l/2 inches into the body of the wall and that the major part of the By inspection of Figs. 1 and 2 it will be seen that bricks 11 and 13, forming a header course, break joints with the stretcher course therebelow, shown in dotted lines in Fig. 2.

I have shown the stretcher bricks to constitute three courses. It is, of course, manifest that the header course may follow any desired number of stretcher courses.

Bricks 11 and 13 are equivalent in length to a standard brick and together may be laid interchangeably therewith.

13 is substantially a three-quarter brick,

and 11 is unequarter brick in Width.

I have used the term header brick to mean those brick which are laid in the Wall with their longest axes in planes transverse to the face of the wall, or at right angles thereto, and Stretcher brick means the brick which have their longest axes parallel with the face of the Wall.

It will be observed that the face of Fig. 3 is made up entirely of stretcher brick which properly break joint with adjacent brick.

Having described my invention, What I claim as new and desire to secure by Letters Patent, is z- 1. A brick facing for a load supporting brick Wall, said wall made of bricks of uniform length, said facing composed of bricks not exceeding one half the length of the bricks of the load supporting Wall and tied to said wall by overlapping brick joints.

2. A iire brick facing for a load supporting Wall composed of permanently placed brick of uniform length to form a wall faced with fire brick in which the bricks are overlapped to break joints and in which the removable fire-brick facing does not exceed one-halt the length 0f a brick in said Wall and which permits the facing lire brick to be removed Without disturbing the remaining bricks in the wall.

3. A Wall in which the header bricks, having their longest axes at right angles to the axes of the runner bricks, are composed of brick members three quarters of the length of standard runner bricks and brick members one quarter the length of standard bricks, the longest member of the header, breaking joint with the runner bricks below, and the shorter member serving as a part oi the Wall facing.

4. A brick Wall having a facing of brick 'with their longest axes parallel with the longest axis of the wall and tied by over lapping other brick back of the facing, facing brick one half the width of the tying brick in front of the tying brick.

A brick Wall having a brick facing in which the header bricks o'verlie the stretcher bricks which form parts 0f the facing and ln'eak jointtherewith, and stretcher bricks, in front ot the header bricks in the same course, and which also constitute parts of said facing.

6. A brick Wall having header courses in which the header bricks extend part way over the stretcher bricks and facing brick located in front of the header bricks and substantially Hush with the stretcher bricks which also constitute parts of said facing.

In testimony whereof I hereunto set my hand.
